Questions about Contax DRS:
(1)Can we compress in GSM codec? How many bps?
(2)Please calculate hard disk space used by each codec.
(1) We have many choices, the GSM 610 is there! It is 13 Kbps (The
lowest one to save Hard Disk space)
(2) Please refer to the Picture, divided by "8" is the Bytes needed
for every second of recording
into Hard Disk. (There's automated Disk back-up for long period
of recording) so, 8K bytes/sec.
for 64 bps,1625 bytes/sec. for GSM 610 (140.4 MB for 24-hour
continued recording) Use a 200 GB HD,
for 16 lines,it can last 3 months. (People do back-up long
Question #17 :

format, and via new driver and buffering
scheme,the sound should be clean without static noise and no
choppy effect in Full-duplex cases.
(3)This new serious is suitable for DRS, IVR and VoIP Bridging
software, where higher sound quality
have its value.
Question #18 :
What is the major difference of voice logging using "Voice
Activate" and "Phone Line Signalling"?
(1)"Voice Activate" approach is based on sound level to START and
STOP (when Silence Time reaches) so,
it may become unreliable when applied to telephone recording.
(As the Line may be
noisy, and calls may come very close intime)
(2)Our Contax DRS 3.0.0 has not just Voice Activation (for Voice
Logging), but it provided Telephony
Signal monitor for "Precised" Telephone Recording.
(3)Some Voice logger may use "cheap" Sound Card for Voice Activated
(4)For Voice Activated solution, try challenge it with
if the FSK Caller ID can be presented faithfully,
(B)Can every call be separated, and not mixed (When two calls come
and Voice Active and Silence Detection not sensitive enough)?
(C)Compared with our Voltage Drop detection method, it is
(D)Can call-in and call-out be detected all the time? And shown
with called numbers?
(E)Can call activity be monitored in "Real Time"?
Question #19 :
I am trying to install this card into a new computer. It is a Tyan
Tomcat i915 motherboard with
a P4 processor. I have this card working in an old Pentium II 450
MHz computer so I know it does work.
When I install the WAVE drivers, the computer freezes. Do you have
any suggestions? The board type is
Talk Voice 8LV Rev.B3. The motherboard is using the Intel 915G
(1)Based on your input, we can do the upgrade of your 8LV, to Rev.
C1, and it should fix the issue
related to Intel 915 chipset and other things.
The procedure is as follows:
(A)You download our EasyTAPI3.0.0 from the following link:
Refer to the document for proper driver replacement &
(2)After you agreed for Remote Upgrade (and paid)

have been to me.
Our new system is up and running perfectly. Have a great day!]
Question #20 :
I just got the 4LV+DRS 3.0.0, it works fine. But, how do I make
sure that the Voltage Drop
Detection setting is working in all the cases?
(A) Make sure Line Tone Detection is NOT "checked" (You can
select GSM 610 format to save HD space)
(B)"Check" Voltage Detection, and set Silence Time to be 600,000
(C)Go to DIAG32, make sure the "LC Drop Detection" is "Checked"
Question #21 :
We need to use TTS for generating dynamic voice (for example Status
of an order, Account balance etc)
Can you please guide me, where to get a Text To Speech Voice for
Indian English accent?
For IVR II 3.0.0, as far as the TAPI is Microsoft SAPI 5.1
compatible (can show up in Control panel's
Speech window for selection), it will run.
You can do Google search for proper TTS suppliers.(Price varies
depending on your voice quality
IVR II 3.0.0 rely on MS SAPI for the TTS component to function.
With paid API service, we can do special interface for TTS of your
Question #22 :
Some customers want IVR system to be linked with existing PABX
How should I make it possible? Should all the telephone cables (from
go into Voice Boards?
Then where to connect with PABX?
For PABX interface, you connect the voice card to "Telephone
Extension" and the IVR II answers
calls just like "people" pick up the phone.
Use the transfer component (with proper property setting) to do the
transfer, based on your PABX's rule.
(e.g. flash at certain duration, pre-fix with XX, etc.) You need to
consult the PABX manual, it varies.
Keep in mind, that the IVR channel is "mimic" human in calling.
Question #23 :
I have a CallURL Talk Voice board with IVR II, in the channel
settings of Runtime Engine,
I found Voice Encoding Format list, where I am getting all options
with 8 khz. Is it due
to this hardware only supports 8khz, 8-bit format?
Normally, 8K x 8 is good enough for ordinary usage. As telephone
line is only 8K x 8 PCM.(Make sure
you record the file in 8K x 8 PCM format, not 16 x 8K: For TTS,
select the 8K x 8 PCM output format.)
For customer willing to pay for better quality, CallURL will soon
introduce a new product
(Tentatively code name TRu-Sound) that supports 16-bit audio format
and with new DSP and driver code,
a much cleaner audio, among other enhancement for bridging between
PSTN and VoIP in Full-Duplex mode.
Please contact us, or the website for details.
Question #24 :
Can’t get Caller ID, what should I do?
A few things may worth for checking:
(1) Please make sure the Caller ID exist. (Verify with a phone)
(2) Set the DTMF or FSK type correctly.
(3) Close other TAPI applications, then run "Diag32 (Line Detector)
it's in EasyTAPI tools folder"
under Settings --> TAPI Settings, make sure the Call
Parameters "Report Incoming call" is set
to "2" or bigger. As CID may coming between first and 2nd
(4) It may be a good idea to check the wiring that signal is good to
(5) With in DIAG32 (Under tap "Tools", there's one item called Tone
You can click "Record.." and then make a call, afterward,
try to "hear" if the Caller ID is within the recorded wave
(6) You can also send the file to us for verify that the CID is
(A lot of times, No CID is because it is NOT there)
Question #25 :
I am trying to make call to an outside number to connect it with an
CallURL board does not do it, what can you suggest?
For Talk Voice Card, it only supports “Flash Transfer”, means need
to use the PABX “Flash transfer” to achieve
the transfer from caller to 2nd called party. (Via the first called
party). There’s NO SWITCHING function among its TAPI channels.
In theory, Transfer / Bridging within PC and functions as “virtual
switch” is doable. However, it is not implemented within
Talk Voice Card.
Instead, to support people of those requirements, we have ETS
(Ethernet Telephone Switch) product, (The LAN-based hardware
box we used to offer PCX),it will do (Via our IVR II
3.0.0) from one PSTN line to another one (because it has a build-in
within PC). The ETS-4L is similar to 4LV+ but with build-in PBX
function, it also have a matching ETS-4P, that can connected to
analog phone as extensions.
People used ETS boxes for their small call center projects or
specific tender applications.
Question #26 :
When trying to install Talk Voice board, it seems
over-riding/deleting an onboard sound card’s drivers. The syndrome
as soon as it runs through the install process, it “wipes away” the
sound card drivers and people can’t see the sound card at
all from Devices Manager on the control panel.
The reason is that in some model of PC, their BIOS is pre-set to
only support the “first” found PCI Audio Device.
CallURL Voice Board is a “Voice Device”, so as it been detected, the
BIOS won’t look for other “on-board” sound device
(Note, on-board sound device is treated as PCI device, but scanned
Most of time, you can go to CMOS BIOS setting, and look something
like “Advance, PCI Peripheral Setting, in Audio Device
change the setting to “Enable” instead of “Auto” to allow the
on-board audio also been detected.
For the actual details, depending on PC make and model as BIOS is
different. Your customer may need to get support in BIOS
setting from their PC manual or seller.
Question #27 :
How to using Contax IVR II with CallURL 4LV+ voice card to forward
Incoming call to another Outgoing call
You need rely on External PABX that has the “switching” capability
to do it.
The 4LV+ did not including the switching function within the
Although you may notice that our PCX/ETS product can do “call
following”, but, it is because the ETS is a different hardware
(Ethernet Telephone Switch) as it has building switching capability.
As for how to interface the External PABX, the IVR call-flow needs
to follow the spec. defined by the External PABX. Basically,
it it can be done by human, the CX IVR II should be able to mimic
Question #28 :
I have 2/4 LV+ TAPI boards, when using KDTele Tools to play wave
files, the sound has intermittent (Shuttled) breaks.
What can I do?
(1) Make sure that your audio format is ACM 8K X 8-bit u-law.
(If you demand 8K X 16-bit format, please check with us for a
(2) We support our software partner (KDTele tools) with a special
(To take care the buffer size mis-matching issue)
The same version, can also work with TAPIEx from HotWind Software.
(3) You can download "Updatepack200604006.zip"
then do the following:
(A) Unzip it to a folder
(B) Copy Tvm4lvf.sys to "X:\WINDOWS\system32\drivers" (Where X
is the Hard drive you installed EasyTAPI).
(C) Copy voxdrv.600 to "X:\WINDOWS\system32" (Where X is the
Hard drive you installed EasyTAPI).
(D) Restart the PC to effective the changes.
This will solve the sound play issue.
Question #29 :
I have the Talk Voice Boards that used work with Hang-up tone
setting. But, when I moved to a new area where
(after checked with recorded wave)
has no Hang-up tone. I checked with local phone company,they
that they used Loop Current
(LC) Drop as the indicator for Hang-up from the other party.
What can I do?
(1) Please download from
www.callurl.net/download/voctapi.zip and Unzip it, then
copy to C:\windows\system32 to overwrite the old files.
If your EasyTAPI is not installed in C:, change as is)
There are 2 files in the Zip file.
voclib32.dll dll for Talk voice card
voctapi.tsp Tapi driver for Talk Voice card.
(2) Make sure that you checked LC Drop detection box in Hang-up
setting when running DIAG32. (As shown below)
(3) Re-boot and run your hang-up test again. It should hang-up based
on LC drop. (For no Hang-up tone case)
